Yorkshire Terrier and Pug Mix (Yug): Complete Breed Guide

The Yorkshire Terrier and Pug mix — often called the Yug or Pugshire — pairs two of the most popular toy breeds in the United States into one compact, personality-packed companion. With the Yorkshire Terrier ranking 13th and the Pug ranking 31st in AKC breed popularity, it's no surprise that breeders began crossing them to produce a small dog with the Yorkie's silky coat potential and the Pug's easygoing charm.

But here's what many prospective owners don't realize: designer mixes are inherently variable. A Pug-Yorkie cross from the same litter can look, behave, and even shed completely differently from its siblings. This guide breaks down exactly what you can expect — and what you can't — when considering this mix.

Parent Breed Breakdown: Yorkshire Terrier vs. Pug

Understanding the parent breeds is the single most important step in predicting what a Yug might be like. Each parent contributes a distinct set of traits, and the offspring can land anywhere on the spectrum between them.

Parent Breed Comparison: Yorkshire Terrier vs. Pug

Trait	Yorkshire Terrier	Pug
AKC Group	Toy	Toy
Weight Range	4–7 lb (1.8–3.2 kg)	14–18 lb (6.4–8.2 kg)
Height	7–8 in (18–20 cm)	10–13 in (25–33 cm)
Coat Type	Long, silky, single coat; hair-like	Short, smooth, double coat
Shedding	Very low	Moderate to high (seasonal blows)
Muzzle Shape	Mesocephalic (normal length)	Brachycephalic (flat-faced)
Energy Level	Moderate; alert and feisty	Low to moderate; playful bursts
Typical Temperament	Bold, vocal, confident, sometimes territorial	Sociable, clownish, eager to please
Lifespan	11–15 years	13–15 years
Trainability	Moderate; can be stubborn	Moderate; food-motivated

The Yorkshire Terrier originated in northern England in the mid-1800s, bred by mill workers to catch rats in textile factories. Despite their tiny size, Yorkies carry genuine terrier drive — they're bold, curious, and not afraid to bark at dogs ten times their size. The Pug, by contrast, traces back over 2,000 years to ancient China, where they served as companion dogs for Tibetan Buddhist monks and later Chinese emperors. Pugs were bred purely for companionship, which explains their deeply social, people-oriented nature.

When you cross these two, you're blending terrier tenacity with companion-breed sociability. The result can be wonderful — or challenging — depending on which parent's traits dominate.

How Big Will a Yorkshire Terrier and Pug Mix Get?

Size is one of the more predictable aspects of this cross, simply because both parents are toy breeds. However, the weight gap between a 4-lb Yorkie and an 18-lb Pug means there's meaningful variation.

Yug Size Range Estimates

Measurement	Low End (Yorkie-Dominant)	Typical Range	High End (Pug-Dominant)
Adult Weight	7 lb (3.2 kg)	10–15 lb (4.5–6.8 kg)	18 lb (8.2 kg)
Adult Height (at withers)	8 in (20 cm)	9–12 in (23–30 cm)	13 in (33 cm)
Body Build	Lean, fine-boned	Compact, moderate bone	Stocky, barrel-chested

Most first-generation Yugs land in the 10–15 lb range. If the Pug parent was on the larger side or the Yorkie parent was a "teacup" (a non-standard, ethically controversial size category), expect the puppy to skew toward one end of the spectrum. You generally won't know the adult size with certainty until the dog is 9–12 months old.

Understanding Generations: F1, F1B, F2, and Multigen

Coat Types, Shedding, and the Hypoallergenic Question

This is where the Yorkshire Terrier and Pug mix becomes genuinely unpredictable — and where prospective owners are most often surprised.

The coat possibilities fall into three categories:

1. Yorkie-dominant coat: Long, silky, single-layered hair that grows continuously and requires regular trimming. Low shedding. This is the coat type most breeders advertise, but it's not guaranteed in F1 crosses.
2. Pug-dominant coat: Short, dense double coat with a soft undercoat. Moderate to high shedding, especially during seasonal coat blows in spring and fall. Minimal grooming beyond weekly brushing.
3. Blended coat: Medium-length, slightly wavy or wiry texture. Moderate shedding. This is the most common outcome in F1 crosses and often the least predictable to maintain.

Is the Yug hypoallergenic? No designer mix can be guaranteed hypoallergenic. If the puppy inherits the Yorkie's single coat, it will be low-shedding and potentially better tolerated by people with mild dog allergies. However, dog allergies are triggered by dander and saliva proteins (primarily Can f 1 and Can f 2), not hair length. A low-shedding dog still produces dander. If allergy management is your primary reason for choosing this mix, spend extended time with the specific puppy before committing, and consult an allergist.

Temperament: What to Expect (and What to Prepare For)

Temperament in mixed breeds is the hardest trait to predict because behavior is shaped by dozens of genes interacting with early environment, socialization, and training. That said, the Pug and Yorkie parent breeds have well-documented behavioral tendencies that give us a reasonable framework.

Temperament Variability Chart

Trait	Best-Case Scenario	Challenging Scenario	Influencing Parent
Sociability	Friendly with strangers, outgoing, eager to greet visitors	Wary of strangers, alert-barks excessively, slow to warm up	Pug (social) vs. Yorkie (territorial)
Vocalization	Occasional bark, generally quiet indoors	Frequent barking at sounds, doorbell, passersby	Yorkie (highly vocal terrier)
Separation tolerance	Comfortable alone for 3–4 hours with proper conditioning	Severe separation anxiety, destructive when left alone	Both breeds are companion-oriented; prone to attachment
Playfulness	Playful but not hyper; enjoys short games and cuddling	Overly rambunctious or, conversely, uninterested in play	Pug (clownish play) vs. Yorkie (terrier chase drive)
Child compatibility	Gentle and tolerant with respectful children ages 8+	Snappy if handled roughly; fragile around toddlers	Both (small size = injury risk; Yorkie may nip)
Dog-to-dog social skills	Gets along with other dogs after proper socialization	Feisty with larger dogs; may trigger fights by not backing down	Yorkie (terrier boldness)
Trainability	Responsive to food rewards; learns basic cues within 2–3 weeks	Stubborn, easily distracted, slow to housetrain	Pug (food-motivated) vs. Yorkie (independent)

Key socialization window: Puppies have a critical socialization period between 3 and 14 weeks of age. During this window, expose your Yug puppy to at least 100 novel but positive experiences — different surfaces, sounds, people wearing hats, other vaccinated dogs, car rides, handling of paws and ears. The AVMA recommends structured early socialization as the strongest predictor of stable adult temperament in any breed or mix.

Training approach: Use positive reinforcement exclusively — small, high-value treats (freeze-dried liver, tiny pieces of boiled chicken), clicker marking, and short 5-minute sessions. Both Pugs and Yorkies shut down under harsh correction. Never use shock collars, prong collars, or alpha rolls on any dog, but especially not on a toy-breed mix where physical punishment can cause injury and lasting fear.

Health Considerations: Hybrid Vigor, Myths, and Real Risks

Let's address the hybrid vigor claim head-on: crossbreeding does not guarantee better health. The concept of heterosis (hybrid vigor) is real in livestock genetics, but in companion dogs, the health benefit of mixing two breeds is modest at best — and it does not eliminate inherited conditions that both parent breeds share.

A 2018 study published in Canine Genetics and Epidemiology found that mixed-breed dogs did have a slightly lower incidence of some inherited disorders compared to purebreds, but the difference was smaller than commonly claimed. What matters more is whether the individual parents were health-tested.

Conditions Inherited from the Pug Side

• Brachycephalic Obstructive Airway Syndrome (BOAS): If the Yug inherits a shortened muzzle, stenotic nares (narrowed nostrils), or an elongated soft palate, breathing difficulties can range from mild snoring to exercise intolerance and heat stroke risk. The Merck Veterinary Manual describes BOAS as one of the most significant welfare concerns in flat-faced breeds.
• Pug Dog Encephalitis (PDE): A rare but fatal inflammatory brain disease unique to Pugs. While extremely unlikely in a cross, the genetic predisposition can theoretically be passed on.
• Hemivertebrae: A spinal malformation common in screw-tailed breeds including Pugs. Can cause hind-limb weakness or paralysis in severe cases.
• Corneal ulcers and eye injuries: Prominent eyes (if inherited) are vulnerable to scratches, dry eye, and progressive retinal atrophy (PRA).

Conditions Inherited from the Yorkshire Terrier Side

• Patellar luxation: The kneecap slips out of place, causing intermittent skipping or lameness. Very common in toy breeds; graded I–IV by veterinarians. Surgical correction (if Grade III or IV) typically costs $1,500–$3,000 per knee.
• Portosystemic shunt (PSS): A congenital liver blood vessel abnormality. Symptoms include stunted growth, disorientation after eating, and seizures. Diagnosis requires bile acid testing and ultrasound; surgical correction costs $3,000–$6,000+.
• Tracheal collapse: Weakening of the cartilage rings in the windpipe, causing a characteristic "goose honk" cough. Managed with weight control, harness-only walking (never neck collars), and sometimes medication or surgery.
• Dental disease: Toy breeds have disproportionately large teeth for their small jaws, leading to severe crowding and early periodontal disease. Expect professional dental cleanings under anesthesia ($400–$800 per session) starting as early as age 2–3.
• Legg-Calvé-Perthes disease: Degeneration of the femoral head (hip joint) in young small-breed dogs, typically presenting between 5–8 months of age. Requires surgical removal of the femoral head; prognosis is generally good with physical therapy.

Shared Risk: Obesity

Both Pugs and Yorkies are prone to weight gain, though for different reasons — Pugs because of food obsession and lower activity, Yorkies because owners often over-treat small dogs without realizing that even a few extra calories have outsized impact on a 10-lb body. A Yug at ideal body condition score (BCS 4–5 out of 9) should have a visible waist when viewed from above and ribs that are easily felt but not visible.

Grooming, Exercise, and Daily Care Requirements

Your Yug's grooming routine depends entirely on which coat type they inherit. Plan for either scenario before you bring the puppy home.

Grooming by Coat Type

Coat Type	Brushing Frequency	Professional Grooming	Bathing	Estimated Annual Cost
Yorkie-type (long/silky)	Daily with a pin brush and metal comb	Every 6–8 weeks ($50–$80 per session)	Every 2–3 weeks	$450–$750
Pug-type (short/double)	2–3 times per week with a rubber curry brush	Rarely needed	Monthly or as needed	$50–$100
Blended (medium/wavy)	3–4 times per week with a slicker brush	Every 8–10 weeks ($40–$65 per session)	Every 3–4 weeks	$200–$400

Universal care needs regardless of coat type:

• Nail trims: Every 2–3 weeks. Overgrown nails alter gait and contribute to patellar luxation stress.
• Ear cleaning: Weekly with a veterinarian-approved ear cleanser, especially if ears are floppy (Pug-inherited). Floppy ears trap moisture and promote yeast infections.
• Dental care: Daily tooth brushing with enzymatic dog toothpaste. This is non-negotiable for toy breeds. Add VOHC-approved dental chews (such as Greenies or CET chews) if the dog tolerates them.
• Facial fold care (if Pug-faced): Clean facial wrinkles 2–3 times per week with a damp cloth or veterinary wrinkle wipe to prevent fold dermatitis and yeast overgrowth.

Exercise Requirements

Yugs need 30–45 minutes of daily activity, split into two or three short sessions. This is less than most breeds but more than owners of small dogs often provide.

• Morning: 10–15 minute leash walk at a moderate pace
• Afternoon: Indoor play session — fetch, tug, or puzzle toy work for mental stimulation
• Evening: 10–15 minute walk or supervised yard time

Heat caution: If your Yug inherits any degree of brachycephaly (shortened muzzle), they are at elevated risk for heat stroke. Avoid outdoor exercise when temperatures exceed 80°F (27°C). Watch for excessive panting, blue-tinged gums, or collapse — these are emergencies. Always use a harness rather than a neck collar to avoid tracheal pressure.

Estimated first-year total (breeder puppy)	$2,110	$3,380–$5,210	$7,350+

Breeder vs. rescue availability: Yugs are not among the most common designer mixes (unlike Goldendoodles or Labradoodles), so availability through breeders is somewhat limited. You'll find them most often through small-scale breeders in the Midwest and Southern United States. When evaluating a breeder, require proof of health testing on both parent dogs — specifically OFA patella evaluations, cardiac exams, and (for the Pug parent) a BOAS assessment. Responsible breeders will also have a take-back clause in their contract.

Rescue availability is sporadic. Check breed-specific rescues for both Yorkshire Terriers and Pugs — organizations like Yorkshire Terrier Club of America rescue networks and Pug rescue groups occasionally take in mixed-breed dogs. Petfinder and Adopt-a-Pet allow you to search by mix type, and you may find Yugs listed under "Terrier mix" or "Pug mix" rather than by their designer name.

Who Is the Yorkshire Terrier and Pug Mix Best Suited For?

This mix works well for specific lifestyles and can be a poor fit for others. Here's an honest assessment:

Ideal owners:

• Apartment or condo dwellers who want a compact companion that doesn't need a yard
• Adults or families with children ages 8 and older who understand gentle handling of small dogs
• People who work from home or have flexible schedules — Yugs do poorly with 8+ hours of daily solitude
• First-time dog owners willing to invest in puppy socialization classes and positive-reinforcement training
• Older adults seeking a moderate-energy lap dog for companionship and short walks
• Allergy-sensitive individuals who understand that low-shedding is not guaranteed in this cross and are prepared to meet the specific puppy first

Potentially poor fit:

• Families with toddlers or very young children — the injury risk to a 10-lb dog from rough handling is real
• Owners who are away from home 10+ hours daily without a dog walker or daycare arrangement
• People seeking a guaranteed non-shedding dog (consider a purebred Yorkie or a Poodle mix instead)
• Those in extremely hot climates who cannot manage indoor climate control — brachycephalic risk makes heat management critical
• Multi-dog households with large, high-prey-drive breeds — a 10-lb Yug is vulnerable in rough play

Frequently Asked Questions

What two breeds make up the Yorkshire Terrier and Pug mix?

The Yug is a cross between a purebred Yorkshire Terrier and a purebred Pug. Both parent breeds belong to the AKC Toy Group. The Yorkshire Terrier contributes terrier ancestry, a potentially low-shedding coat, and bold temperament. The Pug contributes ancient companion-dog lineage, a sociable disposition, and a brachycephalic (flat-faced) skull structure that may or may not be inherited by offspring.

How big will a Yorkshire Terrier and Pug mix get?

Most adult Yugs weigh between 10 and 15 lb (4.5–6.8 kg) and stand 9 to 12 inches (23–30 cm) at the shoulder. However, the range extends from as small as 7 lb (3.2 kg) to as large as 18 lb (8.2 kg) depending on which parent's size genes dominate. Growth is typically complete by 10–12 months of age.

What will the temperament of a Yug be like?

Expect a blend of the Pug's sociable, clownish nature and the Yorkie's alert, confident terrier personality. Most Yugs are affectionate with their families, moderately playful, and enjoy being near their people. Challenges can include excessive barking (Yorkie influence), separation anxiety (both breeds), and stubbornness during training. Early socialization between 3–14 weeks is the single most impactful thing you can do to shape a stable temperament.

Is the Yorkshire Terrier and Pug mix hypoallergenic or low-shedding?

Not guaranteed. If the Yug inherits the Yorkie's single coat, shedding will be minimal and the dog may be better tolerated by people with mild allergies. However, many Yugs inherit the Pug's double coat, which sheds moderately to heavily. No dog is truly hypoallergenic. Allergy-sensitive individuals should spend at least 30–60 minutes with the specific puppy before making a commitment and consult a board-certified allergist.

What health issues might this mix inherit?

Key risks include patellar luxation (kneecap dislocation), tracheal collapse, dental disease, and eye problems from both parent breeds. From the Pug side, brachycephalic obstructive airway syndrome (BOAS) is the most significant concern if the puppy inherits a shortened muzzle. From the Yorkie side, portosystemic shunt (liver vessel abnormality) and Legg-Calvé-Perthes disease are less common but serious. Always consult your veterinarian for breed-appropriate screening and maintain annual wellness exams throughout your dog's life.

How much does a Yorkshire Terrier and Pug mix cost?

Breeder prices typically range from $800 to $1,500, though puppies from breeders who perform full health testing on parent dogs may cost up to $2,500. Adoption through a rescue typically costs $250–$500. Budget an additional $2,500–$4,500 for first-year expenses including veterinary care, food, grooming, supplies, and pet insurance.

Are Yugs good with children?

Yugs can do well with gentle, respectful children ages 8 and older. Their small size (typically 10–15 lb) makes them vulnerable to accidental injury from toddlers or young children who don't understand how to handle a small dog. Teach children to never pick up the dog without adult supervision, to avoid squeezing, and to let the dog retreat when it walks away.

How long do Yugs typically live?

Based on the lifespans of both parent breeds, a healthy Yug can be expected to live 12–15 years, with some individuals reaching 16 or 17 years with excellent preventive care, weight management, and regular veterinary checkups.
